Cleaning Ford 302 fuel injectors
I think i have one fuel injector not working. I purchased a pigtail for the injectors, and a 9v battery (found something on google that said to use a 9v battery to activate the injector) and i used my mouth to blow air through (so far) 4 of the 8 injectors. I found one that air would not pass through. I suspect it is clogged since it clicks but wont flow.
How do I clean these injectors? Do they have to go to a shop or can I clean them myself? Any way to test the spray pattern? The air flow trick only tells me that the injector flows, not how well it sprays.
